    Abstract: With an infrared radiator, the surface temperature of which is kept constant during measurement, a measuring area on a roughened material surface is thermally irradiated with oblique incidence of the rays. The temperature of the reflected thermal radiation is measured by an infrared thermometer, which is arranged above the measuring area in such a way that the reflected radiation falls into the area of coverage of the infrared thermometer. The entire measuring area of the material surface which lies in the field of coverage of the infrared thermometer must be thermally irradiated. The measured temperature variation of the reflected radiation in dependence on the known surface roughness of the material is stored in a comparison device. This comparison device is fed a set value for the desired surface roughness. The infrared temperature of a material surface, initially unknown with respect to its surface roughness, is measured and compared with the stored temperature variation, in order to determine the magnitude of the surface roughness. From the value thus obtained and the set value fed in, a differential signal is formed, which is fed via the output of the comparison device to a control of a treatment device for the material.

    Abstract: An apparatus for drying a liquid layer deposited on a carrier material which is moved through a drying zone, which liquid layer contains evaporable solvent components and non-evaporable components, comprises a drying apparatus (1) with a drying channel (2), through which the carrier material band (4) runs in the longitudinal direction, on which band the liquid layer to be dried is deposited. The drying channel has a gas/air permeable channel covering surface (7), through which a gas flow, in particular a heated air flow, flows into the drying channel. The channel covering surface (7) is inclined in relation to the channel bottom surface (3) which runs horizontally. The drying channel (2) is adjoined by a gas exchange chamber (15) which contains a fan (12), the fan outlet (16) of which is directed towards a heat exchanger in a partition wall (10) between the gas exchange chamber (15) and a drying chamber (5) situated above the drying channel (2). The gas exchange chamber (15) contains a choke device (13 and 14 respectively) in its bottom surface (18) and in its upper gas inlet (19) respectively. The drying apparatus (1) further contains an exhausting fan (9) which is arranged above the covering surface of a through-channel (20) and is connected to the through-channel via a suction opening. In the outlet (11) of the exhausting fan (9) there is also a choke device (8). … …
